Industry Context & Processing Challenges: Optical lens barrels, camera module brackets, and sensor housings are thin-walled aluminum or magnesium die-castings. Machining requires precise internal bores, sealing faces, and thread seats without structural flexing or internal optical axis misalignment.
Technical Requirements: Bore circularity and concentricity within ≤0.003 mm, and surface finish Ra<0.05 μm to prevent internal stray light reflection.
ZWH Tooling Solutions & Value: ZWH PCD end mills and single-crystal diamond fly-cutters execute high-speed light milling. Their ultra-sharp cutting edges cut cleanly without pushing material, ensuring accurate thin-wall geometries and burr-free chamfers essential for precision optical assemblies.
